Graphite GC Ferrules
Supplier: Trajan Scientific and Medical
Graphite ferrules are commonly used in GC systems on the inlet and detector ends because they don’t stick to the column, and can be removed and reinserted easily. They should not be used with GC/MS instruments because of permeability to air.

O-Ring seals for GC columns, Therm-O-Ring™, Supelco®
Supplier: Merck
Inlet liners used in an GC require an O-ring placed near the top for proper operation. This O-ring ensures that the only path for carrier gas to get to the outside of the inlet liner is through the grooves in the inlet seal at the bottom of the injection port.

Vespel® Graphite GC Ferrules
Supplier: Trajan Scientific and Medical
Vespel/graphite GC ferrules are made from quality polyimide/graphite blend. They seal with minimal torque and can be reused and repositioned along capillary columns if not over compressed in the fitting. Due to slight shrinking at high temperatures, they must be retightened after initial temperature cycles to avoid leaks.
